| Abstract: | This paper analyses the b_j map and reduced-dimension b_j map of a logic function with partial variables negated, based on which, a graphic method of calculating first-order and second-order Boolean difference of a logic function by using b_j map and reduced-dimension b_j map is proposed. The examples prove that this method has the features of intuition and simplicity, by which the simplest AND/XOR expression of Boolean difference can be obtained. |
